This fixed it for me:

Firstly, I was testing Qt5-5.9.6, so this may not apply for the
current Qt5 version on SBo at the moment, but I built Qt5 with an
extra configure option:

-c++std c++11 \

I also added -std=c++11 to CXXFLAGS.

For mlt change

CFLAGS="$SLKCFLAGS" \
CXXFLAGS="$SLKCFLAGS" \

to

export CFLAGS="$SLKCFLAGS"
export CXXFLAGS="$SLKCFLAGS -std=c++11"

and comment out or remove the old make line and add just 'make' so it looks
like this

make clean
make 
make install DESTDIR=$PKG
